At its bottom, the container 1 is Briefly, the device functions in the following formed to provide a discharge spout'4 which isv manner:- controlled by a flap valve 5. When the container l is empty, the float I4 is The top of the container l is closed by a r ein lowered position and, as seen in Figure 1 of container I. a

' seats, the port I2 in the valve I Iisbrou'ght into the drawings, the conduit 8 is closed by the valve II, said conduit communicating with the container I through the ports 20, the valves 25 being in open position. It will thus be seen that suction from the milking machine to the cow must be through the container land consequently the first milk flowing through the tube 9 enters said container I. This suction in the container I maintains the flap valve 5 in closed position; After a predetermined quantity of the milk has entered the container I, the float I4, of course, rises. This brings the valves 25 into contact with the substantially concave seats 2| and the closing of theports 20 by said valves 25 is then completed by the suction from the'milking'machine, thereby stopping the flow of milk to the As the valves 25 engage their communication with the conduit 8 for opening said conduit 8 and the rest of the milkthen flows,

from the cow through the suction-tube -9 in the usual-mamier to the receptacle of-the -milking machine. -By utilizing the suction from the V milking'machine-for completing the closing'of the valves'25, said-valves are caused toseat very quickly after being brought into contact with the seats-ZI-by the float I4, aswillbe apparent. As will also be apparent, this constr-uctionrand are rangement assures'against leakage. Itwill further be seen that the conduit '3 is opened for the passage of themi-lk therethrough substantially simultaneously with or immediately after the closing of the valves 25 As thevalve I i is raised to open position, the channel I8 therein is brought into communication with the vent, port I9 for breaking the vacuum in-the container I, thereby permitting theilap valve 5 to openfor discharging the milk which has been collected in a the container I into the receptacle 2. It has been found that the float M may be causedto drop, when nosuction is inthe tube 9 of the milking machine, by simply shakingthe container Ior the cover I5, therebyreturning the-valve II to closed position and the valves 25 to open position. It isibelieved-that thermally-advantages of a device constructed in accordance Withthe present invention will be readily understood, 4 and although thepreferred embodiment of the invention'is as illustrated and described,-it -is tobe understood that 'ch'angesin'the details ofwconstruction and in the combination and arrange ment of parts'may'be;resorted;to-=whichr-will fall within" the scope ofitheiinvention as claimed.

' What is claimed is:-

1. The combination with a milking machine eluding a suction line for drawing milk from a cow, of means interposed in said suction line for diverting a quantity of the milk, said means including a container communicating with the suction line for receiving the milk therefrom, in-

terconnected valves controlling the suction line and the communication between said suction line and the container, and common-meansforactuating the valves. H r v 2. The combination'with a milking machine in 'cluding a suction linefor drawing milk from-a cow, of means interposed in said suction line for diverting a quantity of the milk, said means inmeans controlling the communication between the container and suction line, valve means controlling said suction line, the ,first named valve means being 'openwhen the-secondnamed valve *cluding a container communicating with the suc-L tionline for receiving the milk therefrom, valve means is closed, and common means for actuating connected with 'the valve'means for actuating same.

4. The combination with a milking machine including a suction line for "drawing milk from a 'cow," of meansinterposed insaid' suction line for diverting 'a' quantity of the milk, said means including a container, a conduit on the container interposed in the "suction line, 'saidconduit communicating with the container, a valveicontrolling the' cond-uit, a float connected to'rthe valve and operable in the container, andva'lves connected with the first named valvexfor controlling the communication between the conduit and the container, the second named valves being open when the-first named valve :is closed.
